How does sonysve 14a 16fgh deal with automatic shutdown and flashback? Now it automatically shuts down for no reason.

This problem is more complicated. Automatic shutdown and flashback are mainly related to hardware. It may be that the hardware is occasionally short-circuited, the heat dissipation is poor and the temperature is high, and it will automatically shut down.

Check the running status of CPU first: Is the heat dissipation normal? Replace a CPU as much as possible to ensure that the CPU is normal;

Remove external components: such as CD-ROM drive, sound card board, hard disk and other external components to ensure that there is one optical board, and whether the retest cycle is normal. At the same time, conditional attention should be paid to the standby current above 1A during the test.

Pay attention to the main process: whether the heat dissipation is normal-whether the external equipment is normal-whether the CPU is normal-whether the motherboard is normal. Through this process, the problem can be determined. If it is a motherboard problem, it can only be sent for repair.
